CARBURETER.

Specification of Letters Patent.

Patented May '7, 1907.

Application filel September 1'7, 1906. Serial No. 334.015.

To all whmn it puny concern:

Be it known that we, ANDERs AKEsoN and VERNER G. ANDERSON, citizens of the United States, residing at the. city and county of WVorcester and State of Massachusetts, have invented certain new and useful improve ments in Carbureters, of which the following is a specification.

Our invention relates to carbureters, of the class that is buried in the ground, and is an apparatus arranged to receive from a proper source compressed air and to pass the same over a volatile hydrocarbon, such as naphtha or gasolene, for the purpose of mingling said air with the hydrocarbon vapor in order to produce an illuminating gas of great lighting power.

WVith this object in view, our invention consists of the novel construction and combination of parts,- as hereinafter described and specifically set forth in the claims.

Similar reference numerals in the drawing and in the specification indicate similar parts of the apparatus.

The figure represents a central longitudinal sectional View of our improved carbureter.

1 designates a vertically arranged cylindrical tank, which is closed by a top plate 2 and a bottom plate 3. Centrally of the top plate 2 of the tank is secured a depending guide 4 arranged to have a sliding fit in a tubular head 5, which has an integral flange 6. A circular gas-dome 7 is provided with a central opening to receive the lower end portion of the tubular head 5, and said dome is secured to the flange 6 of said head by rivets 8. The outer portion of the dome or gas holder 7 terminates with a downwardly and inwardly directed flange 9.

10 designates a collapsible carbureting bag, made of burlap or other suitable absorbent material and formed into a series of rings whose inner and outer edges are sewed together and constituting a succession of accordion folds. Said bag 10 has its upper ring or layer of burlap secured by rivets 11 to the inclined flange 9 of the gas-dome 7.

A hydrocarbon supply pipe 12 leads to a valve-casing 13, secured to a housing 14, which in turn is secured to the side of the tank 1, and said housing has its chamber in open communication with the chamber of said tank. In the casing 13 is formed a valve-seat to receive a conical valve 15 having an integral depending stem 16.

The

upper end of said casing 13 is covered by a screw-cap 17, in which is secured the end of.

the hydrocarbon supply pipe 12, and between said cap 17 and said valve 15 is interposed an expansive coil spring 18 to force against and tend to keep said valve closed upon its seat. The housing 14 has a bifurcated portion to receive a pivot center 19 of the rod connection 20 of a ball-float 21, and one end of the rod connection of said float 21 is adapted to contact with the depending stem of the valve 15 in lifting the same from its seat, while the hydrocarbon liquid is admitted through the pipe 12, such liquid falling into the tank and fills the same, to the level indicated by the dotted line 22.

When the liquid has reached this level the float has risen to such a height as to permit of the spring 18 closing the valve 15, thereby preventing further ingress of the hydrocarbon liquid, while the level 22 is maintained.

Centrally of the bag 10 isan inverted U shaped yoke comprising two vertical rods 23, having knobs 24 secured on their lower ends to rest upon the bottom plate 3 of the tank 1, and the upper portion of said rods terminating with a central upwardly projecting screw threaded stem 25, which is secured in the tubular head 5 of the gas-dome 7. This yoke acts as a support for the gas-dome and is of such height as to permit the flange portion 9 of said dome being submerged in the hydro* carbon liquid, during the time that the hydrocarbon vapors are filling within said dome. When the tank has been charged with the hydrocarbon liquid, to the normal level de scribed, air is forced through the pipe 26, which leads up above the level of said liquid and thence passes through branch pipe connections 27 that discharge the air beneath the level of said liquid. As the vapor accumulates 'within the gas-dome, said dome rises, and as the bag 10 is carried up by said dome its accordion folds open. Thus, when the dome has reached its upward position, indicated by dotted lines, the carbureted vapor within the dome passes through the bag and fills the upper portion of the tank, and the distended portion of said bag serves to throw off the evaporation or absorbent vapors held in suspense, when the bag was entirely submerged in the liquid. As the uption indicated by dotted lines.

perportion of the bag rises above the level of the hydrocarbon liquid, an evaporation of said liquid takes place and its volatile elements pass off in vapor. From the tank the gas eventually emerges through pipes 28, which extend from above the level of the liquid, to the point of consumption.

The extent of movement of the gas-dome 7 is limited by means of a disk-plate 29, which is secured to the yoke-rods 23, said disk coming in contact with and closing the air-discharge openings of the pipes 27, to the posi- As the level of the hydrocarbon liquid falls, the float 21 will fall with it, and will open the valve 15, which will remain open until the liquid has been restored to its former normal level, this operation of alternately opening and closing the valve 15, being automatically performed and serving to maintain the hydrocarbon liquid at substantially a constant level in the apparatus. A drainage or pump-out pipe extends from near the bottom of the tank 1, to a point above the ground, thepurpose of this pipe being to provide for the withdrawal of any condensed moisture that may accumulate at the bottom of said tank.

What we claim and desire to secure by Letters-Patent, is

1. In a carbureter, the combination of a vertical closed tank adapted to contain a hydrocarbon liquid a guide centrally secured to i the top of said tank; a tubular head. to receive said guide; a gas-dome centrally secured upon said head, and said dome having its outer portion terminating with a downwardly and inwardly directed flange; a carbureting bag of absorbent material formed into accordion folds whose upper layer is secured to the flange of said dome; a yoke secured to said head to support said dome so that its flange may be submerged in said liquid; an air-inlet-pipe extending above the level of the liquid in said dome and beneath the surface of said liquid; a disk secured upon said yoke to close the discharge end of said pipe beneath the level of said liquid; a gas-discharge-pipe extending from above the level of said liquid in the tank; an oilfeed-pipe, and a governing valve constructed to maintain said liquid at substantially a constant level within said tank.

2. In a carbureter, the combination of a closed tank adapted to contain a hydrocarbon liquid; an inlet-pipe arranged to discharge air beneath the level of said liquid; a gas-dome above said pipe; a support carried by said dome; a disk secured to said support to close the air discharge from said pipe when the dome has reached its highest limit of travel; a collapsible carbureting bag of absorbent material surrounding said pipe and secured to said dome; a housing secured to said tank and having its chamber in open communication with the interior of the same; a casing mounted on said housing; an oilfeed-pipe communicating with the chamberof said casing; a spring pressed valve within said casing; a float connection pivotally mounted. in said housing to open said valve, and a gasoutlet-pipe extending from above the level of the liquid in said tank.

3. In a carbureter, the combination with a closed tank having an oil feed-pipe and a governing valve to maintain the oil at substantially a constant level within said tank, of a gas-dome whose outer portion enters beneath the level of said. liquid; a carbureting bag of absorbent material having its top secured to the outer portion of said dome; a yoke Within said bag, carried by said dome to support the latter above the level of said liquid an inlet-pipe below said dome to discharge air beneaththe level of said li uid a disk carried by said yoke to close off t e discharge of air from said pipe and at the same time prevent further upward movement of said dome, and a gas discharge-pi e extend.- ing from above the oil level in sai tank.

4. In a carbureter, the combination of a closed tank adapted to contain a hydrocarbon liquid; an automatically operated valve constructed to govern the inlet of said liquid to a normal level within said tank; a gasdome having its open end submerged in said liquid; a tubular head centrally secured upon said dome; a guide secured to the top of said tank and having a sliding lit in said head; a support carried by said dome to prevent further downward movement of the dome in said liquid; a carbureting bag of absorbent material surrounding said support, formed into accordion folds and having its top secured t0 the open end portion of said dome; a pipe to discharge air beneath the level of said liquid within said bag; a disk secured upon said support to close off the airsupply from said pipe when said dome has reached its upward. limit of movement, and a gas outlet pipe from above the level of the liquid within said tank;

In testimony whereof we affix oursignatures in presence of two witnesses.
